SMOKE-CONSUMER.

SPECIFICATION formingpart of Letters Patent No. 731,373, dated June 16, 1903.

Application filed March 12,1902.

To all whom, it may concern.-

Be it known that I, JAMES M. KERSEY, of

West Virginia, have invented certain new and useful Improvements in Smoke-Consumers, of which the following isacomplete specification, reference being had to the accompanying drawings.

My invention relates to smoke-consumers generally, and particularly to'that class of smoke-consumers which by promoting combustion within a furnace or the like prevent the emission therefrom of smoke or other unconsumed products of combustion.

The object of my inventionis to produce a simple and efficient device which may be readily adapted for use in any style of stove, furnace, or the like for supplying a volume of pure air to the interior of a combustion-chamber in such condition and at such a point as to produce perfect combustion therein, and thus to eliminate the objectionable outpouring therefrom of smoke or other undesirable matter.

In the drawings I illustrate one form of my device adapted for use in an ordinary boilerfurnace; but it should be understood that the details of construction may be widely varied to meet existing conditions which may govern its installation without any departure from the spirit of my invention.

In the accompanying drawings, Figure I is a side elevation of a boiler-furnace, partly in section, showing one form of embodiment of my device adjusted therein ready for use. Fig. II is a vertical section of the subjectmatter of Fig. I. Fig. III is a detail view of the lower front wall of the furnace, illustrating means for regulating the operation of my device. Fig. IV is a perspective view of a portion of my device detached.

Referring to the numerals on the drawings, 1 indicates a boiler of usual type, and 2 the enveloping wall thereof. The front Wall of the furnace is broken by furnace-doors 3 and ash-pit doors 4. Suitably supported by the front wall of the furnace and by a bridge 5 I provide grate-bars 6, which define between the several walls of the furnace the usual combustion-chamber 7 and ash-pit 8.

10 indicates a pipe of suitable and preferred Serial No. 97,905. (No model.)

phere and is there provided with a damper 11 of usual design. Extending through the combustion-chamber, the pipe 10 terminates at its end opposite the front wall in a close joint with an elbow 12, which curves upward and makes a tight joint with the rounded base of a gradually-flattened head 15. The head 15 is in the form of embodiment illustrated herewith-fan-shaped and at its top substantially coextensive witha throat 17, defined by the top of the bridge 5 and the lower edge of a plate 18, secured to the boiler 1.

In operation the ,pipe 10 is so located with respect to the grate-bars as, when the furnace is in operation, to be entirely su rrounded by the bed of coals upon the grate-bars. By this means the pipe is, during thetime that a fire is maintained within the furnace, kept at white heat. Air being admitted by manipulation of the damper passes through the pipe toward the head 15, whence it issues heated to a high degree and mingles with the flame of combustion as it passes toward the throat 17. It will be apparent that the heated air supplied from the head 15 is pure at the time of its mingling with the flame within the furnace, and it is by means of so supplying unvitiated air to the flame of combustion that my invention is adapted to produce perfect combustion, and thus prevent the emission of smoke from the furnace.

It will be apparent that in the absence of the depending plate 18 the flame of combustion and the partially-consumed productsof combustion will curl around the lower curved portion of the boiler, and thus escape the positive mingling with the heated air from the head 15, which is essential in practice. However, any means may be employed for forming a throat or regulating the means of egress of flame from the combustion-chamber.

Ordinarily the small amount of smoke which would escape before the pipe, elbow, and head become sufficiently heated would not be considered objectionable but, if desired, means may be employed forimpartiug initial heat to the elbow. I illustrate one means, which consists in the provision of a door 21 in a side wall of the furnace, by means of which fire may be started under the elbow and the elbow heated before the volume of smoke becomes considerable. I also show the bridge 5 as provided with a recess 22 in order that the fire-bed may be extended beyond the elbow and its proper degree of heat always maintained.

It will be understood that the form of embodiment of my invention illustrated and described herewith is simply shown by way of example and that the device may be varied in many ways without departing from the scope of the principle of my invention. For instance, the pipe 10 may be provided with means of steam-supply to its interior in order to prevent burning out or it may be supplied with a waterjacket; but this is simply suggested as one of the many devices which in practice may be used to ad vantage in connection with my invention.

What I claim is- 1. The combination with a combustion chamber, as of afurnace, and a bridge therein, of a fan-shaped head transversely disposed within said chamber in proximity to, but out of contact with said bridge, whereby part of the products of combustion pass between said head and the bridge, and part
